What this shows Japan's Innovation Score is 28.9/100 (29th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Japan?

Each dot is one of Japan’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Japan’s own 12.7 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Japan's grants concentrate

Japan Capacitor Industrial Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 64.3% of grants classified under H01G (CAPACITORS; Capacitors, Rectifiers, Detectors, Switching Devices, Light-sensitive OR Temperature-sensitive Devices OF THE Electrolytic Type). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Japan sits between Jiangsu Shemar Electric Co., Ltd. and Joma-Polytec GmbH.

Japan's three-year grant acceleration

Japan Capacitor Industrial Co., Ltd. shows 2 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
